Detailed Description

Parsed expression.

Expression is label with possibly some additional information.

Form: name[(+|-)offset][=literal] e.g. myDataStructLabel+8=16, myCodeLabel=3, myDataStructLabel+8 or myDataStructLabel

Part after '=' sign is just value of label, if value is always resolved by compiler and it is also given by user values will be compared to match.

Offset can be used for example with structures, if one want's to refer different datafields.
